State of matter Flashcards

1
Q

Solid

A

Can be melted

Definite shape

Made up of particles

Strong attractions

Made up of particles in fixed position

Can be condensed

Strong connection between particles

A solid is where the particles have a very strong bond and are forced together. Solids are different to liquids are gasses because they don’t have a as strong bond as solids do. But one thing they have in common is all the particles vibrate

Q

Gases

A

Contain partials free to move

Made up of particles

Easy to compress

Expand to fill a container

Can be poured

Can be poured

Weaker connection between particles

A gas is where the particles are freely to move and have no connection with each other. This is different to a liquid and a solid because a liquid and a solid always as some sort of connection and are always touching. The strength of the forces between the gas particles are weaker than solids and liquids.

Q

Liquid

A

Made up of particles

Can be poured

Weak connection between particles

A liquid is where the particles are like friends but not best friends so this means they have a bond but not a strong bond. Liquid is different to solids and gases because a liquid is the only state of matter that can be poured. A liquid vibrates more than a solid.

Q

Saturated

A

When no more solute can be dissolved in a solvent

17
Q

What does solvation mean?

A

The interaction of solvent and a solute

18
Q

Calculate Rf

A

Divide the distance travelled by the component by the distance travelled by the solvent.

19
Q

What is solubility?

A

How easily something dissolves

20
Q

What do you see when the solute has been put into the solvent?

A

I see the solute going into the solvent and the solvent is breaking the solute away and finally it turns into a solution

21
Q

What are the separation techniques?

A

Distillation, crystallisation, fractional distillation, evaporation, filtration, Distillation, Magnetic Separation, Sieving and Chromatography.
